Spinning reel for casting to tuna

[Sea Flat]

I enjoy running and gunning around for tuna. To be honest, in the past I have gone out way undergunned. My wife got me a gift certificate to a local tackle shop. I was thinking of getting the Fin-Nor Offshore 85, but someone recently told me that I would have to change out the drag after 2 fish or so. Is this right? Are there other reels that are in a similar price range that are better than the Fin-Nor Offshore? Obviously, if money were no object I would just get a Stella, but I can not justify spending that $$ on a reel when i only target tuna 5-10 times a year.

Thanks in advance.
